In the rapidly evolving electronics manufacturing and repair sectors of New Zealand, the quality of your consumables directly dictates the reliability of your final product. For importers, distributors, and wholesalers looking to penetrate the Kiwi market, sourcing the right materials is paramount.
We present our premium wholesale high quality 60 40 flux core solder wire, available in versatile 250g and 500g reels, and in a comprehensive range of diameters including 1.2mm, 1.6mm, 2.3mm, and 3.25mm. Manufactured by XF Solder, a specialized factory with decades of expertise in tin solder production, this product is engineered to meet the rigorous demands of professional electronics assembly, circuit board repair, and general metal joining applications across New Zealand.

New Zealand has a vibrant technology sector, from DIY enthusiasts in Christchurch to large-scale manufacturing in Auckland. The common denominator is the need for reliable, high-performance solder. Our 60 40 flux core solder offers the perfect balance of workability and joint strength. The 60% tin and 40% lead composition provides a low melting point, ensuring fast wetting and minimizing the risk of heat damage to sensitive electronic components.
For New Zealand importers, stocking a product that caters to both the industrial sector and the hobbyist market is a strategic advantage. Our reels are packaged specifically for wholesale distribution, ensuring that your inventory remains fresh and ready for sale.
Understanding that different applications require different tools, we offer our 60 40 flux core solder wire in four distinct diameters, all packaged in convenient 250g and 500g reels.
The 60 40 flux core solder 1.2mm diameter is the industry standard for precision through-hole soldering on printed circuit boards (PCBs). Its fine gauge allows for controlled application, preventing solder bridges between closely spaced pads. This size is perfect for:
PCB assembly and rework.
Repairing consumer electronics.
Fine detail work in robotics and prototyping.
The 60 40 flux core solder 1.6mm is the most versatile diameter in our lineup. It strikes an ideal balance between wire strength and melt speed. It is thick enough to deliver adequate solder volume for larger joints but remains manageable for standard electronic work. This is the go-to choice for:
General electrical repairs.
Audio equipment assembly (jacks and potentiometers).
Automotive electrical system repairs.
When working with larger terminals, heavy-gauge wires, or lug connections, the 60 40 flux core solder 2.3mm diameter is required. This thicker wire delivers the necessary volume quickly, ensuring efficient workflow on larger projects. It is commonly used for:
Soldering battery lugs and connectors.
Heavy industrial control panels.
Large gauge wire splicing.
The largest diameter we offer, the 60 40 flux core solder 3.25mm, is designed for high-volume soldering tasks. While excellent for large electrical connections, its robust nature also makes it suitable for certain sheet metal fabrication and non-potable plumbing applications (where lead content is permissible for industrial use). It ensures rapid joint filling and structural integrity.

As a dedicated manufacturer, XF Solder does more than just produce solder; we engineer reliability. Our wholesale 60 40 flux core solder is manufactured under strict quality controls to ensure consistency in alloy composition and flux core percentage. This consistency is critical for achieving repeatable, high-quality solder joints.
The New Zealand market values local brands and trust. We understand that as an importer, you want to build your own brand identity. Therefore, XF Solder offers comprehensive customization services. We can print your company logo and specifications directly onto the 250g and 500g reels. This allows you to present a professional, branded product to your customers, fostering brand loyalty and premium positioning in the marketplace.
By dealing directly with the factory—XF Solder—New Zealand importers eliminate middleman costs. This direct relationship allows us to offer highly competitive wholesale 60 40 flux core solder pricing. Whether you are stocking a local hardware chain in Wellington or supplying manufacturing plants in Hamilton, our volume pricing ensures you maintain healthy profit margins.
The primary application for our 60 40 flux core solder lies in the electronics sector. The 60/40 ratio is a eutectic alloy, meaning it transitions almost instantly from a liquid to a solid state. This reduces the chance of "cold joints" and mechanical stress during the cooling process, making it ideal for sensitive circuit boards.
For PCB assembly, the flux core is essential. The flux cleans the metal surfaces, removing oxidation and allowing the solder to flow smoothly. Our high-quality flux is halide-free and low in spatter, ensuring clean boards and reducing post-soldering cleaning requirements. This is why our 60 40 flux core solder 500g reels are a favorite among high-volume electronics manufacturers.
Beyond electronics, this solder is highly effective for joining various metals, including copper, brass, and tin-plated steel. Whether for electrical grounding, metalwork repairs, or crafting, the strong molecular bond created by the 60/40 alloy ensures durability.

To assist New Zealand importers and their customers, we have compiled a list of frequently asked questions regarding our 60 40 flux core solder wire.
The "60 40" refers to the alloy composition: 60% Tin and 40% Lead. This is the most common tin/lead ratio used in electronics because it offers a relatively low melting point (approximately 183°C to 190°C) and excellent wetting characteristics.
The 60 40 flux core solder 250g reel is ideal for hobbyists, technicians, and light repair work. It is lightweight and easy to handle. The 60 40 flux core solder 500g reel is designed for production environments and serious enthusiasts who go through large volumes of solder, offering better value and less frequent reel changes.
1.2mm: Best for fine PCB work and small components.
1.6mm: Best all-purpose diameter for general electrical and electronic work.
2.3mm: Best for larger joints, terminals, and heavier gauge wires.
3.25mm: Best for high-speed, high-volume industrial soldering and large metal joining.
While technically it can join copper pipes, 60 40 flux core solder contains lead. In New Zealand, lead-based solder is prohibited for use on drinking water supply lines due to health risks. It is perfectly acceptable and widely used for electronic repairs, stained glass work, and industrial non-potable water systems or gas lines (check local codes).
Absolutely. We specialize in helping our wholesale partners build their brand. We offer customized reels and labels featuring your logo and branding. This allows you to market wholesale 60 40 flux core solder under your own brand name in the New Zealand market.
Yes. Our 60 40 flux core solder utilizes a rosin-based flux (Type R or RMA) that is activated by heat. It cleans the joint surfaces during soldering and evaporates, leaving a clean, insulating residue that is generally non-corrosive and does not need to be removed for most electronics applications.
